A brief summary of DVTS application and a proposal for DVTS-specific measurement tools

This article provides a brief summary of DVTS applications, explores routing and measurement in DVTS, and proposes DVTS-specific measurement tools. It discusses the challenges of DVTS networks and suggests a proposal for measurement tools to improve the user experience. The proposed tools aim to test and simulate DVTS behavior, identify network bottlenecks, and establish a common language between users and administrators. The architecture of the measurement tools includes Dvmcast sender, Dvping sender/receiver, access interface, server registration, and web interface. The article concludes with a call for international collaboration on DVTS measurement and application activities.

  1. A brief summary of DVTS application and a proposal for DVTS-specific measurement tools Xing Li 2007-04-24

  2. Outline • A brief summary of DVTS application • Applications • Routing • Measurement • A proposal for DVTS-specific measurement tools • Basic tool • Access interface • Find the server alone the path • Server registration

  3. A brief summary of DVTS application

  4. DVTS features • Hardware is based on consumer products • Software is free and open source • Useful for serious applications • Special demand for network support • 30Mbps, single video stream

  5. Bad cabling Wrong speed Wrong duplex mode Bad cabling Wrong speed Wrong duplex mode AS1 AS2 AS3 access access Bandwidth bottle neck firewall firewall Network challenges

  6. The experience • Rehearses are essential before the real event. • Can we use measure tools to make the life easier?

  7. A proposal for DVTS-specific measurement tools

  8. Design goals • Test without the help of the counterpart • Simulate the real DVTS behavior without using the DVTS system • Built a common language between the application users and the network administrators • Find the bottleneck of the network

  9. The architecture • Basic tool • Dvmcast sender and reflector • Dvping sender/receiver • Access interface • web • Find the server alone the path • AS path and DNS server • Server registration • Manual or automatic

  10. Sending mode DVTS system dvmcast DVTS file Reflecting mode (1) DVTS system dvmcast Reflecting mode (2) dvmcast dvping The operation modes of basic tools

  11. The technical specification dvmcast and dvmping： -p snd_port (8000) -rp rcv_port (8000) -t period(sec) -bw bandwidth (bps/kbps/Mbps) host -4|6

  12. Web interface

  13. Sending mode

  14. Reflecting mode (2)

  15. QS1 (DNS) BGP IP->ASN QS2 (DNS) Data Base ASN->IP Internet User A User B AS=V AS=X AS=U AS=Y AS=Z MS1 MS2 MS3 MS4 MS5 Find the server (1)

  16. Find the server (2)

  17. Server Registration (1) • Manual registration • Automatic registration (under development)
